I've never been in such a situation as this, but have heard from
a number of people who have been "forced" to subscribe to such lists.
Unless it is posting by owner *only* and the notices are infrequent,
very infrequent, a great deal of ill will can be generated.

I would strongly advise against it, even though there is a way you can
keep subscribers from either signing off or setting NOMAIL.
